Description

Technical Field

[0001] This utility model relates to the field of melt filters, and in particular to a special tool for disassembling melt filters. Background Technology

[0002] Melt filters are important equipment in high-speed spinning and fine denier filament spinning. They are used for continuous filtration of polymer melts to remove impurities and unmelted particles from the melt, thereby improving the spinning performance of the melt and ensuring the spinning quality.

[0003] As a core component of the production process, melt filters play a crucial role in purifying the melt and are an important safeguard for ensuring the quality of end products. However, during routine maintenance, operators often face significant safety hazards when installing or removing bolts on these filters. Because the equipment operates at high temperatures for extended periods, the external wall temperature frequently exceeds the human tolerance threshold. Operators face a high risk of accidental contact between their upper limbs and the high-temperature equipment surface during bolt installation and removal, impacting their ability to work normally and posing a serious threat to production continuity and occupational health. Utility Model Content

[0004] The purpose of this utility model is to provide a special tool for disassembling melt filters that can avoid burns during the loading and unloading of high-temperature components.

[0005] To solve the above-mentioned technical problems, this utility model provides a special tool for disassembling a melt filter, including an extension rod, a connecting ring connected to one end of the extension rod, and several connecting ribs detachably connected to the connecting ring. The ends of the several connecting ribs away from the connecting ring are all connected to limiting ribs. The limiting ribs have a hollow structure inside so that the hollow structure matches the parts to be installed or removed.

[0006] Furthermore, the connecting ring is provided with a plurality of locking blocks spaced apart along the circumference, and the end of the connecting rib near the connecting ring is provided with a locking groove that matches the locking block, and a locking plate is movably installed on the side of the locking groove so that when the locking block is engaged in the locking groove, the locking plate limits the locking block.

[0007] Furthermore, several connecting ribs are connected to the fixed core through a positioning plate. The positioning plate has a moving groove, and the card plate is movably installed in the moving groove. An elastic element is connected between the side of the card plate and the moving groove.

[0008] Furthermore, a pressing component is movably mounted at the fixed core, and a pull wire is connected between the pressing component and the card plate. The pull wire passes through the positioning plate and the inner side of the fixed core, so that when the pressing component is pressed, the card plate moves along the moving groove.

[0009] Furthermore, the pressing member is provided with a plurality of limiting pieces along the circumferential direction, and the limiting pieces abut against the fixing core.

[0010] Furthermore, there is a clearance groove between adjacent limiting plates, which matches the pull wire.

[0011] Furthermore, the connecting ring has a support plate on its side, a support rib is provided between the support plate and the connecting ring, and the end of the extension rod is connected to the support plate.

[0012] Furthermore, the end side of the card block has a guide arc surface that matches the card plate.

[0013] The beneficial effects of this utility model are as follows: When it is necessary to install or remove bolts on the melt filter, a suitable limiting rib is selected to ensure that the shape of the hollow structure matches the bolt to be installed or removed. Then, several connecting ribs at the limiting rib are matched and connected to the connecting ring. At this time, the operator can use the extension rod to drive the limiting rib, thereby ensuring the distance between the operator and the high temperature area during the bolt installation and removal process, so as to avoid the possibility of burns to the personnel, and ensuring the compatibility requirements of different bolt installation and removal.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0021] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0022] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0023] like Figures 1-5 The present invention provides a special tool for disassembling a melt filter, including an extension rod 1, a connecting ring 2 connected to one end of the extension rod 1, and several connecting ribs 3 detachably connected to the connecting ring 2. The ends of the several connecting ribs 3 away from the connecting ring 2 are all connected to the limiting ribs 4. The limiting ribs 4 have a hollow structure 5 inside so that the hollow structure 5 matches the parts to be installed or removed.

[0024] When it is necessary to install or remove bolts on the melt filter, a suitable limiting rib 4 is selected to ensure that the shape of the hollow structure 5 matches the bolt to be installed or removed. Then, several connecting ribs 3 at the limiting rib 4 are matched and connected to the connecting ring 2. At this time, the operator can use the extension rod 1 to drive the limiting rib 4, thereby ensuring the distance between the operator and the high temperature area during the bolt installation and removal process, so as to avoid the possibility of burns to the personnel, and ensuring the compatibility requirements of different bolt installation and removal.

[0025] In one embodiment of this solution, when the bolt to be installed or removed is an external hexagonal bolt, the hollow structure 5 is set to a hexagonal structure accordingly. When the shape of the parts to be installed or removed changes, a matching hollow structure 5 can be selected for use.

[0026] Preferably, the connecting ring 2 is provided with a plurality of locking blocks 6 at intervals along the circumference, and the connecting rib 3 is provided with a locking groove 7 that matches the locking block 6 at one end near the connecting ring 2. The locking groove 7 is movably equipped with a locking plate 8 so that when the locking block 6 is locked in the locking groove 7, the locking plate 8 limits the locking block 6.

[0027] Specifically, when connecting the connecting rib 3 and the connecting ring 2, the locking block 6 is engaged into the corresponding slot 7. During the engagement of the locking block 6, the locking plate 8 is pushed away from the locking block 6 to make the opening of the slot 7 open. After the locking block 6 is engaged, the locking plate 8 is reset and moved to limit the upper side of the locking block 6, preventing the locking block 6 from dislodging from the slot 7, thereby ensuring that the extension rod 1 can stably control the limiting rib 4 at each bolt.

[0028] In one embodiment of this solution, the end side of the card block 6 has a guide arc surface 19 that matches the card plate 8, so that when the card block 6 is engaged with the card slot 7, the guide arc surface 19 can guide and push the card plate 8, making the card plate 8 easier to move.

[0029] Preferably, a plurality of connecting ribs 3 are connected to the fixed core 10 through a positioning plate 9. The positioning plate 9 has a moving groove 11, the clamping plate 8 is movably installed in the moving groove 11, and an elastic element 12 is connected between the side of the clamping plate 8 and the moving groove 11.

[0030] Specifically, the card plate 8 moves along the moving groove 11 to a position away from the card slot 7, so that the card block 6 can smoothly enter the card slot 7. When the card plate 8 needs to be reset, the elastic element 12 pushes the card plate 8 to reset, which can ensure the limiting effect of the card plate 8 on the card block 6.

[0031] Among them, the elastic element 12 can be a spring structure.

[0032] Preferably, a pressing member 13 is movably installed at the fixed core 10, and a pull wire 14 is connected between the pressing member 13 and the card plate 8. The pull wire 14 passes through the positioning plate 9 and the inner side of the fixed core 10, so that when the pressing member 13 is pressed, the card plate 8 moves along the moving groove 11.

[0033] Specifically, when disassembling and replacing different limiting ribs 4 on the connecting ring 2, press the pressing member 13 to move it down along the fixed core 10. At this time, the pressing member 13 simultaneously pulls several pull wires 14, causing the pull wires 14 to pull the card plate 8 to retract towards the inside of the moving groove 11. This allows the card block 6 to quickly disengage from the card groove 7, ensuring convenient disassembly of the connecting ring 2. After disassembly or installation, the card plate 8 can be reset by the elastic member 12, and then the pressing member 13 can be raised and reset by the pull wires 14, ensuring the normal use of the pressing member 13 in the future.

[0034] The guy wire 14 can be made of steel wire, metal rope, etc.

[0035] Preferably, the pressing member 13 is provided with a plurality of limiting pieces 15 along the circumferential direction, and the limiting pieces 15 abut against the fixing core 10.

[0036] Specifically, the pressing member 13 is limited by the limiting piece 15, so that the upper and lower sides of the pressing member 13 can be limited by the limiting piece 15 and the pull line 14 respectively, thereby ensuring the stability of the pressing member 13 in the initial position.

[0037] Preferably, there is a clearance groove 16 between adjacent limiting pieces 15, and the clearance groove 16 matches the pull wire 14.

[0038] Specifically, since the pull wire 14 needs to connect the pressing member 13 and each card plate 8, the pull wire 14 will inevitably pass through the side of the pressing member 13. The limiting piece 15 limits the pressing member 13 on the side. At this time, the setting of the relief groove 16 can effectively ensure the stability of the respective functions of the limiting piece 15 and the pull wire 14, and avoid interference, wear and other problems between the pull wire 14 and the limiting piece 15.

[0039] Preferably, the connecting ring 2 has a support plate 17 on one side, and a support rib 18 is provided between the support plate 17 and the connecting ring 2, and the end of the extension rod 1 is connected to the support plate 17.

[0040] Specifically, at the connection position between the extension rod 1 and the connecting ring 2, a support plate 17 and a support rib 18 are provided so that the support rib 18 can increase the structural stability between the support plate 17 and the connecting ring 2, thereby ensuring the stability of the extension rod 1 and increasing the effect of the extension rod 1 in controlling the rotation of the limit rib 4 bolt.

[0041] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
